Man Plans......God Laughs

I took it out yesterday for a test run and all went beautifully. The clutch was working perfectly. A nice three finger pull. I was stoked. Woo Hoo!! Finally, sucess. I put the bike away and decided to get up in the morning and clean it up a bit and take a longer ride. This morning I put it all together and fired it up and.........THE FRICKEN CLUTCH WOULDN'T WORK!!!!!!!!!!!!!!! After calling the bike and myself a few choice names, I began adjusting all of the various links, the mousetrap, the spring tension.........nothing. As I was about to push the bike outside and set fire to it, I noticed that the pushrod that comes out of the back of the booster was cocking at an angle when I applied pressure. I said to myself, "Self, this cannot be good." I yanked off the booster and made a support plate. Simply a hunk of 2 x 1/8" flat steel with three holes, one in the center drilled to the size of the pushrod and two that fit the mounting studs. I placed shims, (OK, flat washers but shims sounds more professional), between the support plate and the pushrod seal to apply a bit of pressure and keep the vacuum in the can where it needs to be. Works bitchen now.
One suggestion, made by an old hand at this sort of thing, is to install Torrington bearings on the mousetrap and the cable-to-booster bell crank. I will be doing this very soon, but for now, it's working well with the bronze bushings in the mousetrap. The bell crank is steel against steel, so that will be the first thing that I will change. With the lessened friction that the bearings will give me, I think it will be, nearly, perfect.
